ULTRASOUND ASSISTED BATCH OPERATION FOR THE ADSORPTION OF HEXAVALENT CHROMIUM ONTO ENGINEERED NANOBIOCOMPOSITE

Ultrasound assisted batch operation for the adsorption of hexavalent chromium onto engineered nanobiocomposite

The study demonstrates the comparative retention characteristics of chromium from aqueous environment on iron(III) cellulose nanocomposite bead under conventional (C-ads) and ultrasound assisted (U-ads) batch adsorption operation.Optimization of process parameters was achieved varying pH, contact/sonication time, initial Cr(VI) concentration, adsor
